I'm having a weird problem here. I upgraded a Windows XP computer from IE6 to IE8 yesterday and everything seemed to work normally until today. Now I can't open any browser on this computer. The computer had Google Chrome installed and it suddenly disappeared, I installed it again and now it dowsn't open either. I also installed Firefox and the same thing happened. The computer had no anti virus, I installed Ad-Aware, run a full scan and it detected some malware, but browsers are still not working

Any ideas?

Check your process list for anything suss, and install some real AV. Because it really does sound malicious code to me... – shadow Nov 14 '12 at 5:16

Sounds like the computer is infected with some type of malware, that is running a constant "kill xxx" command, causing certain apps to not be able to run. If anti-virus software is unable to clean it, I'd say just wipe and re-install the OS, this should fix the problem.

Finally I solved the problem by restoring the PC to a previous state before installing IE8 and installed a decent antivirus, it seems to be working fine now :)
